VR Preview disable in 4.11.1

After install 4.11.1 update, VR Preview not work (icon button disable), reinstall Oculus runtime not solve.
I’m using windows 10 and Oculus DK2…

4.11.1 uses Oculus SDK 1.3 so you will need to install Oculus Home to use VR preview (Setup Your Oculus: Quest, Quest 2, Link, Rift S & Rift | Oculus - 844MB downloaded during install. Unreal editor will need to restart if you are switching runtimes). FYI DK2 is fully compatible with Oculus Home despite the warning message in-app, but if you want to use oculus share demos still, you will have to set up runtime switching (use google).

Thank you very much…
